A comprehensive analysis of Google Apps for Android reveals potential upgrade plans to improve Google assistant functionality Google has taken another big step in improving its smart assistant experience. The Android system will store and analyze users' voices to gain more "personalized voice recognition" capabilities
Access:
Storing and analyzing a person's voice will improve response time and accuracy because the user's voice and common words will be familiar to Google assistants. Assistants can also access Google's servers, and summaries of other users' voice models will be summarized and analyzed. This function may also enable more accurate recognition of voice commands and contact names.
Due to privacy issues, I believe Google will leave an option in the settings. If users do not want the voice to be stored anywhere, they can choose to exit personalized speech recognition.
Of course, the deep mining of APK is not always accurate, and some functions may not appear in future versions.
